Water chemistry and land cover attributes for The Loch and Sky Pond, Rocky Mountain National Park Water chemistry and land cover attributes for The Loch and Sky Pond, Rocky Mountain National Park
Water chemistry and land cover attributes for The Loch and Sky Pond, Rocky Mountain National Park. These data were part of a larger survey (data from other sources) used to describe drivers of change to mountain lake productivity.
Analysis of Escherichia coli, total recoverable iron, and dissolved selenium concentrations and loads for 303(d) listed segments in the Grand Valley, Colorado, 1991-2018 Analysis of Escherichia coli, total recoverable iron, and dissolved selenium concentrations and loads for 303(d) listed segments in the Grand Valley, Colorado, 1991-2018
The U.S. Geological Survey, in cooperation with Grand Valley Drainage District, Colorado Water Conservation Board, Colorado Department of Public Health and Environment, and Colorado River Water Conservation District, conducted a loading analysis for selected constituents and tributaries in the Grand Valley, Colorado, to support the development of total maximum daily loads (TMDL) at...
Liquid water content of summertime coastal California fog events, San Mateo County Liquid water content of summertime coastal California fog events, San Mateo County
Measurements of liquid water content (LWC) of coastal fog events were collected using specialized fog water collection units during the hot dry summer season (July to September) and continued through the winter. These data were assembled to explore the potential of fog water collection as a water resource for Midpeninsula Regional Open Space District public lands in San Mateo County...
Cholinesterase inhibition in butterflies on the National Key Deer Refuge following aerial application of a mosquito control pesticide Cholinesterase inhibition in butterflies on the National Key Deer Refuge following aerial application of a mosquito control pesticide
The data set contains raw data for pesticide (naled) residues on samplers collected after aerial applications over the National Key Deer Refuge in the Florida Keys, and biological response (cholinesterase activity in butterflies and mosquito mortality) for organisms co-located with the residue samplers.
Baseflow estimation and hydroclimatic data input details for the Upper Rio Grande, 1980 to 2015 Baseflow estimation and hydroclimatic data input details for the Upper Rio Grande, 1980 to 2015
Understanding how changing climatic conditions affect streamflow volume and timing is critical for effective water management. In the Rio Grande Basin of the southwest U.S., decreasing snowpack, increasing minimum temperatures, and decreasing streamflow have been observed in recent decades, but the effects of hydroclimatic changes on baseflow, or groundwater discharge to streams, have...
Assessment of uncontained Zequanox applications in a Midwestern lake data Assessment of uncontained Zequanox applications in a Midwestern lake data
We applied Zequanox using a custom-engineered, boat mounted application system to replicated 0.30 Hectare plots within a small inland lake. The objectives of these applications were to determine if uncontained, open-water Zequanox applications could effectively control zebra mussel populations and protect native unionid mussel populations within zebra mussel infested systems. The...
